15-hexadecynoic acid Usage And Synthesis

Description

Alkynyl palmitic acid can be used to identify and characterize the post-translational S-palmitoylation of proteins with Click Chemistry.

Uses

15-hexadecynoic acid is a form of palmitic acid with an ω-terminal alkyne. The terminal alkyne group can be used in linking reactions, known as click chemistry; this chemistry is characterized by high dependability and specificity of the azide-alkyne bioconjugation reactions. The use of palmitic acid alkyne and related lipids in isolating palmitoylated proteins has been described.

Uses

Palmitic acid (15-yne) has been used as a component of fatty acid probe stock solution for the optimization of Alk-C16 incorporation onto cellular proteins. It is also suitable for metabolic labeling.

Biochem/physiol Actions

Alkynyl palmitic acid (aPA) is a modified palmitic acid with an ω-terminal alkyne. The terminal alkyne group can be used in a highly specific linking reaction with azide-containing reagents, known as ‘click chemistry′. The click chemistry reactions are rapid, convenient, versatile and regiospecific. They are easy to purify. aPA can be used for isolating palmitoylated proteins.
